This is a question that has been annoying me for quite some time. If a photon does not experience time then Doesn't that mean that a photon exists in only 3 dimensions? If so, then does that mean that other 3d objects can exist in our 4d space? What about an object that only has 2 dimensions? Can a 2d object exist in 4d space also? Any clearing up on this topic would be appreciated.
